Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only illustrative and should not be construed as imposing any limitation on the scope of the present invention.
FIG. 1 illustrates the architecture of one embodiment of the pilot cognitive assessment system of the present invention. Referring to fig. 1, the system of the present embodiment includes: the system comprises a memory evaluation subsystem, an attention evaluation subsystem, an intelligence evaluation subsystem, a spatial perception evaluation subsystem, a reaction evaluation subsystem, a professional ability evaluation subsystem and a total evaluation subsystem.
The 6 subsystems correspond to 6 dimensions respectively constituting the cognitive ability of the pilot: memory, attention, intelligence, spatial perception, responsiveness and professional ability.
Therefore, the above six dimensions are used as the content of the cognitive ability of the pilot, please refer to the following basis.
In general, the invention proposes an evaluation dimension suitable for testing the cognitive ability of pilots based on various tasks and scenarios that the tested personnel encounter in flight:
because the pilot needs to memorize the capability of different types (characters, numbers and voice) of information such as an operation manual, system knowledge, standard propaganda, airplane state, flight information, navigation station guidance information and the like, and needs to complete corresponding work according to the memorized content, for example, the flight height of the airplane is adjusted according to the given height of the navigation station. Therefore, the pilot recognizes the need to investigate the memory of the tested person.
Because the pilot needs the ability to operate the airplane, monitor instruments, monitor the external environment of the airplane, navigate communication, monitor alarm signals and other two or more tasks at the same time, for example, the pilot needs to put the airplane form to a designated position during approach landing and communicate with the ground navigation station at the same time. Thus, pilot awareness requires the attention of the tested person.
Because not all emergency handling conditions are written in a manual or trained, the pilot needs to have reasoning capability in the process of finding and solving the fault, for example, the pilot controls the aircraft to be forced to land only through thrust changes of two engines after all hydraulic systems of an aviation accident layer are failed.
The pilot needs to identify his exact position in the air, especially in the absence of avionics assistance, and can identify the general orientation from terrain and compare it to the chart.
The pilot should have the reaction force under the emergency condition to reasonably operate the airplane to guarantee safety, if the pilot listens to the air collision avoidance system for warning, the airplane should be immediately controlled to the proper direction, and if the pilot finds that the speed is less than a threshold value in the process of taking off and running, the runway is invaded, and the taking off should be immediately stopped.
Because a large number of instruments exist in the aircraft, a pilot controls the aircraft to be in a correct course and a correct attitude according to information in the instruments under most conditions, the position (course) on the circumference needs to be quickly judged in the navigation process, the linear scales such as an altitude zone can be quickly estimated, and professional capabilities such as speed estimation capability, estimated arrival time estimation capability, glance capability and the like, and key information in a cockpit can be quickly mastered are needed.
In summary, according to the specific situation that the pilot needs to deal with in the flight mission, it is found that the above six dimensions can more completely cover the cognitive abilities required by the pilot in the working process, and whether the tested person has the potential of the pilot can be judged in advance in the pilot selection process through the measurement of the above six dimensions.
The memory evaluation subsystem is used for evaluating the memory of the tested person. The memory evaluation subsystem comprises a character memory evaluation module, a digital work memory evaluation module, a path memory evaluation module, an audio memory evaluation module, a scene memory evaluation module, a character memory evaluation module, an action memory evaluation module and a post-deduction memory evaluation module.
The character memory evaluation module is configured to: a plurality of (for example, 10) Chinese words appear at the same time and last for a certain time (for example, 40s), after the words disappear, the same number of (for example, 10) different words appear in turn and independently, and whether the words appear before or not is asked to evaluate the word memory ability of the tested person.
The digital memory evaluation module is configured to: a plurality of (for example, 10) multi-digit numbers (for example, three-digit numbers) appear at the same time for a certain time (for example, 40s), the same number of (for example, 10) different multi-digit numbers (for example, three-digit numbers) appear sequentially and independently after the numbers disappear, and whether the multi-digit numbers (for example, three-digit numbers) appear before or not is asked to evaluate the digital memory capacity of the tested person.
The digital working memory evaluation module is configured to: sequentially displaying a plurality of (for example, 2) lighted lattices (for example, nine lattices), displaying numbers in one lighted lattice, and after displaying for a plurality of times (for example, four times), calculating the sum of historical numbers in a certain lattice so as to evaluate the digital work memory capacity of the tested person. An example is shown in fig. 2.
The path memory evaluation module is configured to: in a large square formed by square grids of n times n (n is a natural number larger than 1, for example, 6 times 6), 1 square grid is lightened randomly and then is extinguished quickly (for example, 1 square grid is displayed randomly as red for 0.75s), the process is repeated for multiple times (for example, 3 to 4 times), and positions where the lightened square grid (red square grid) appears in all times are selected to evaluate the path memory capacity of the tested person. Referring to fig. 3, a solid square represents a lighted square.
The audio memory evaluation module is configured to: according to the voice content within a certain number of words (such as 30 words), questions related to the voice content are answered to evaluate the audio memory capacity of the tested person.
The scene memory evaluation module is configured to: displaying a scene picture containing a plurality of (for example, 4) special articles, keeping displaying for a certain time, then disappearing (for example, 4s), answering what article appears at one position (for example, question mark position) after the scene picture disappears, and evaluating the scene memory ability of the tested person.
The character memory evaluation module is configured to: displaying a multi-digit number (such as 5 digits) for a certain time (such as 1.5s), randomly appearing a certain number after the multi-digit number disappears, and judging whether the randomly appeared number appears in the previously displayed multi-digit number (if the randomly appeared number appears, pressing a space key) so as to evaluate the character memory ability of the tested person.
The action memory evaluation module is configured to: displaying four numbers (such as numbers 1,2, 3 and 4 shown in fig. 4) and keeping for a certain time (such as 3s), remembering the direction keys corresponding to the four numbers, and after a key command is sent (such as a command of 'PRESS' appears), sequentially pressing the four direction keys from small to large according to the sequence of the numbers to evaluate the action memory capacity of the tested person.
